In a 'Jason meets Percy' fanfic, they could meet in a place that is neutral to both of them, like a magical marketplace. Percy is there looking for a special item for his next adventure, and Jason is on a mission to find a way to strengthen his camp. They cross paths and initially have a bit of a misunderstanding. But as they start talking, they find out they have a common enemy in the background planning something big. So they decide to join forces and use their unique skills to stop the enemy.
Maybe in the fanfic, there is a tournament in their world, and Jason and Percy are both participants. Before the actual tournament, they decide to spar with each other to test their mettle. Along the way, they face some challenges like disagreements on the rules of sparring or external distractions, but they work through them.
One possibility is that the gods see Percy and Jason as threats to their power. Maybe they've become too powerful or popular among the demigods. So, the gods plot against them in secret. They could set up a series of seemingly impossible challenges that are actually traps. Eventually, Percy and Jason fall into these traps and are killed. This could lead to chaos among the demigods as they lose two of their most powerful leaders.
One possible plot twist could be that Percy is initially oblivious to Jason's feelings. Then, just when Jason is about to give up, Percy discovers his own hidden feelings for Jason. Another twist could be that there's some external force, like a god or a prophecy, that tries to keep them apart. Or perhaps Jason discovers that Percy has a pre - existing relationship that he didn't know about, which complicates his crush.
Well, in this kind of fanfiction, Jason might start showing his jealousy in various ways. Maybe he'll be snippy with Percy when they interact. For example, he could make sarcastic remarks about Percy's abilities or how he's so popular. He might also try to one - up Percy in front of others, like during a training session or a quest briefing.
A group of rogue demigods could be the antagonists. They are jealous of Percy and Jason's fame and power. They form a secret alliance and start causing trouble for the other demigods. Percy and Jason meet while trying to figure out who is behind these attacks. At first, they suspect each other, but then they realize the real culprits are this group of rogue demigods and join forces to stop them.
One possible plot could be that they meet in a dangerous situation, like a new threat emerging in the demigod world. Maybe they have to team up to fight a powerful monster. Percy's experience with the sea could be combined with Jason's leadership and Leo's mechanical skills to come up with a unique plan to defeat the enemy.
Well, it could be that Littlefoot, the friendly dinosaur, stumbles upon Jason in the forest. At first, Littlefoot is scared because Jason looks so strange. But then, they find out they both have a common goal of protecting the forest. So they team up, with Littlefoot using his knowledge of the land and Jason using his... well, his unique skills to fend off any threats to the forest.
Well, they could start off on the wrong foot. Maybe Jason is a bit too by - the - book Roman and Percy is his carefree Greek self. But then they'd realize they have a lot in common, like their heroic natures. They might team up to fight a common enemy, using their unique powers. Jason with his lightning and leadership skills, and Percy with his water - based powers and street - smart thinking.
Well, one possibility is that they might initially be cautious of each other. Percy, being from the Greek side, and Jason, from the Roman side, have different upbringings in their respective demigod cultures. But they could quickly realize they have a lot in common, like their leadership skills and their powerful abilities. They might end up teaming up to face a new threat that emerges, combining Percy's control over water and Jason's control over the wind and lightning.
Well, it could be about a misunderstanding. Maybe there's a rumor that Percy has done something bad to Jason's friends, so Jason challenges him to a fight. Percy, being Percy, doesn't back down and they start fighting. In the end, they realize it was all a big misunderstanding when the real culprit is found.
